Question

Find the coordinates of the point which is located in the YZ-plane, one unit to the right of the XZ- plane, and six units above the XY-plane.

Answer 1

Let the coordinates of the point be (x, y, z). Since the point is located in the YZ plane, x0. Also, the point is one unit to the right of XZ-plane and six units above the XY-plane.
∴ y = 1, z = 6

Hence, coordinates of the required point are (0,1, 6).
